Right, to pick up where I was yesterday: Steampunk music is rather obviously a rather ecclectic mixture of various stiles. I am still, however, at a complete loss to explain how Vanessa Mae made it into the steampunk list.
Returning to the Traveler Approved™ list of steampunk artist, as I said before, they draw heavily from a goth and also (something I omited yesterday) metal background, some of them (like Rasputina, Vernian Process, Indica, Abney Park and others) play with the aesthetics, others do not. Vernian Process and Abney Park are active in the Steampunk scene, I bet The Deadly Nightshade Botanical Society is, too, again, other bands are propably not.
I have also heard people calling Tom Waits steampunk (he deserves a honorary mention anyway, for taking the part of Renfield in Bram Stoker’s Dracula), Emilie Autumn also is a, to me, obvious choice.
So what we have now is quite a huge range of alternative styles which are liked/prefered by people “in the scene™“.
And what does that mean? Well, I guess it means that there are some bands around which are definitely Steampunk, whose members are active in the scene and there are even more bands which steampunks like. So I am pretty confident in making the following statement: As a steampunk you can listen to whatever the hell you like, you are an individual, not a member of a hivemind, by Jove!
